Why install an automatic suppression system?
"In certain industrial environments, a few seconds are enough for a fire to cause major damage, endanger lives or halt production. An automatic suppression system detects and responds to a fire 24/7 without human intervention, protecting your people, your equipment and your business continuity.
How does an automatic suppression system work?
An automatic suppression system combines fire detection with a device that discharges a suitable extinguishing agent: as soon as a fire is detected, it analyses the situation, triggers the safety procedures and automatically releases the selected extinguishing agent.
Recommended chain Detector → Fire control panel → CMSI → Time delay → Automatic suppression → Feedback.

Key selection criteria
Nature of the risks
Not all fires have the same characteristics. Fires involving hydrocarbons, lithium-ion batteries, electrical equipment or chemicals require different extinguishing agents.
Value of the equipment to protect
Server rooms, data centers, laboratories and electrical rooms require clean agents that leave no residue.
Presence of personnel
Some technologies, such as CO₂, require special precautions when used in occupied areas.
Environmental constraints
The choice of system also takes into account:
- Ambient temperature
- Humidity
- Ventilation
- Room height
- Volumes to protect
Regulatory constraints
Requirements may vary depending on:
- ICPE
- Seveso
- Public-access buildings (ERP)
- Nuclear
- APSAD insurer requirements
- Client specifications

Industrial automatic fire suppression — FAQ
Your question isn't in this list?
Put it to one of our experts.What is the difference between a fire-detection system and an automatic suppression system?
A fire-detection system identifies a fire and triggers alarms or safety devices. An automatic suppression system goes further by automatically discharging an extinguishing agent (gas, water, foam, water mist, etc.) to control or extinguish the fire.
Do sprinklers always extinguish a fire?
Sprinklers are primarily intended to contain or control the fire to limit its spread until emergency services arrive. Depending on the situation, they can also extinguish the fire completely.
Are there solutions for lithium-ion batteries?
Yes. The risks of lithium-ion batteries generally require a combination of technologies: early detection, thermal monitoring, cooling and a suppression strategy adapted to thermal runaway.
Why is maintenance essential?
Maintenance ensures the system's permanent availability, checks the components and preserves the expected performance in the event of a fire.
Combien coûte un système d'extinction automatique ?
Le coût dépend de nombreux paramètres : technologie choisie, volume à protéger, niveau de risque, interfaces avec les autres systèmes et complexité du projet. Une étude technique est indispensable pour établir un devis.
Do automatic systems replace portable extinguishers?
No. Portable extinguishers remain necessary to allow a fast response to localised fires, in line with the applicable regulations.
How long does a project take?
The duration varies with the size of the site and the complexity of the installation. It generally covers studies, design, installation, testing and commissioning.
How can you get a study of your project?
Our engineers carry out a technical analysis of your installations in order to recommend the most suitable suppression technology. You can contact us via our online form or by phone to arrange a first discussion.
Que se passe-t-il après un déclenchement ?
Après une extinction, l'installation doit être contrôlée, les éventuels composants remplacés ou rechargés, puis remise en service conformément aux procédures prévues.
